tar czvf finish.tar.gz latecommand/
  • Then, it can be use at the end of a Debian preseed file :
d-i preseed/late_command string in-target chsh -s /bin/zsh ; \
in-target /usr/bin/tftp ${IP.SRV.TFTP} -c get ${PATH/TO/TFTPD/ROOT}/finish.tar.gz /tmp/finish.tar.gz ; \
in-target tar xzf /tmp/finish.tar.gz -C /tmp/ ; \
in-target /bin/sh /tmp/latecommand/post.sh
